Nearly finished this video lesson. 

​https://www.youtube.com/watch?v=2_Lbj3slZUY&index=8&list=PL23ZvcdS3XPLNdRYB_QyomQsShx59tpc-

Time taken - 3 hours

Difficulty - Advanced beginner - 20+ hours done

Highlights - Nothing new versus other videos from Mackenzie Childs 12 in 12.
                   - 2 models - Exercise and Workout
                   - 2 Controllers
                   - Haml used in the views
                   - Github needed 5 times to change the code

Gems - Simpleform, Bootstrap, Haml.

Overall - Another good drilling session with rails app basics.  Again some deployment tips would help.
